WS14 Friday 03 June 2016
Title: Geophysics and Geomechanics, Jointly Applied to Subsurface Characterization
Room: Schubert 1
Convenors: Adam Cherrett (Maersk Oil)
Ole Jørgensen (Maersk Oil)
Pierre Thore (Total E&P)
Paul Hatchell (Shell)


Workshop description

This workshop is aimed at a multidisciplinary geoscience and engineering audience, particularly those working with de­forming reservoirs and other geomechanical problems outside the oil industry. Much of the work concerning monitoring of dynamic effects can also be applied to problems such as pre­diction of pore fluid pressures before drilling.

This workshop will provide an opportu­nity to share methods and case studies using 4D seismic over deforming reservoirs, but we are also looking forward to submissions on a wide range of monitoring techniques. These can include, but are not limited to, seismic velocities, borehole sonic measurements, micro- and tele-seismic obser­vations, geodesy, satellite altimetry, bathymetry, gravity and other potential field methods. Likewise, submissions are en­couraged on solid- or geo-mechanics modelling techniques linking to geophysics and seismic. The mutual dependence be­tween confining stress, subsurface heterogeneity and elastic properties points the way towards tighter integration of the geophysical and geomechanical disciplines. This workshop is aimed at participants from a range of dis­ciplines, particularly those working with deforming reservoirs and reservoir dynamics in general. Many of the methods to be discussed pertaining to dynamic effects have applications to problems such as the prediction of pore fluid pressures prior to drilling and production injection performance.

A wide variety of work fits into the theme of this workshop. We are calling for abstracts concerned with various types of monitoring, including:

• Use of (Static, 3D) Seismic Velocities
• Use of 4D Seismic Data
• Borehole Sonic Measurements
• Microseismic Observations
• Teleseismic Observations
• Geodesy, Satellite Altimetry and Bathymetry
• Gravity and Other Potential Field Methods
